misses PATENT caries MLPFI G. BEVANS, OF NORTH QUINCY, MASSACHUSETTS WINDOW SCREEN MOUNTING Application filed November 17, 1932. Serial No. 643,081.

This invention relates to Window screen mountings and has for its object the provision of simple butefltective means whereby the screen will always be centered in the window frame on guides which are permanently attached to the outer bead of said frame, the screen being provided with locking means coacting with said guides under normal conditions and which may be quickly detached from said guides to permit the removal of the screen.

This object is attained by the mechanism illustrated in the accompanying drawings;

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention con- 'sists can be variously arranged and organ ized, and the invention is notlimited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings Figure 1 represents a horizontal section through a window frame provided with screen guides embodying a part of the present invention.

Figure 2 represents a front elevation of said window frame with a screen mounted therein and provided with locking means ooacting with the guides of said window frame, said screen with its locking means forming anotherpart of said invention. 7

Figure 3 represents a horizontal section of a portion of a window frameand showing a screen mounted therein, the cutting plane being on line- 3,3, on Fig. 2.

Figure 4 represents a vertical section on line 4,4, on Fig. 3.

Figure 5 represents an end elevation of a portion of the screen and the end of one of the locking devices mounted thereon.

Figure 6 represents an elevationof a portion of one of the screen guide members.

Figure 7 represents a plan of one of the locking bolts.

Figure 8 represents an elevation of one of the locking bolt casings.

Figure 9 1s a sectional View similar to Fig.

3 showing the locking device without the removable finger grip. 7

Similar characters indicate like parts throughout the several figures of the draw- I In the drawings, 10 is a window casing of usual construction provided at the rear end with vertical side beads 11 between which and the parting beads 12 the upper window sash is adapted to move.

To the oppositely beads 11 are secured U-shaped guide members 13 preferably made of sheet metal bent to form flanges 14,1450 extending toward each other, as shown in Figs. 1 and 3 of the drawings.

The rear flange 14% extends inwardly a distance considerably less than the inward extension of the flange 14.

The window screen frame 15, has. side extensions 16 formed at the rear of the vertical side bars 17 of said frame 15 and extending the entire length thereof, the inner faces of said extensions 16 being separated from the rear faces of the flanges 14w of said metal guide members 13.

The side faces of these extensions 16 are separated from the bead 11 a distance slightly greater than the depth of the flanges 14m.

The side bars 17 of the screen frame 15 have embedded therein housings or casings 18, each having a slidable locking bolt 19 mounted therein.

Each bolt 19 has at its outer end a flattened portion '20, the rear face of which is alined with the front faces of the flanges 14m and is adapted to be moved outwardly to coact with a flange 1403.

When the portions 20 are coacting with the flanges 1400 the front faces of the screen 15 are bearing against the rear faces of the flanges 14, as shown in the drawings.

The flattened portions 20 are preferably formed integral with the cylinder 21 movable endwise in the housings or casings 18 and each cylinder 21 is provided with a shank 22 to the outer end of which is threaded a head disposed faces of the side 0 ITO 23 by whichthe cylinder may bemoved endwise against the tension of a spring 24 within the casing 18.

the fins 27 extending into the wood. of side bars 17.

Theinner ends of-the casings 18 are provided with tubular projections 28 forming bearings for the shanks 22. i

The guide member 13- is finished or colored.

like the bead 11 to'which it is secured so that when one of the window sashes is moved from its normal position the guide member 13 will notbe noticed. H V j When the window is closed the window sashes will hide the guide members 13 fromv view.

heads 23 only at one side of the screen frame 15, while the opposite bolts may be made headless, as shownin Fig. 9.

gers when the bolts '19 are to bewithdrawn.

While one means is'shown whereby the flattened portions are retained in vertical position, it is obvious other means may be employed to obtain the same result.

As-shown in Fig. 2 the screen frame 13 is narrower than the window casing, making it possible to adapt the screen frame to window casings of varying widths or to window 038-:

in s slightly warped. p r

ometimes these window casings are to some extent out of true, that is, their sides are not exactly parallel, but even in these cases the screen frame 15 may be fitted readily thereto. i

There is always a space between the window casing 10 and the outer side edges of the extensions 16 projecting laterally from the bars 17 of the screen frame 15 so that this frame 15 may be moved sidewise to some extent. 7

When the frame 15 is mounted on the guide members the springs 24 in the locking devices will center the same in the window casing. I I

If it is desired to remove the screenframe 15 from the window casing, said frame is moved to the left, as seen in Fig. 2, until theouter edges of side extensions 16 of bars 17 are in contact with the bead 11, the springs 24 in the locking devices at the left of the frame 15 being compressed during this movement. y a v The bolts 19 of the locking devices on the right hand bars are then moved to the left disengaging the flattened portions 20 from the flange 14w, and as soon as. this disen- Theloclring bolts 19 need be provided with gagement has been effected the right side of frame 15 is moved outwardly'beyond the window casing and the frame may then be disengaged from the guide member 13 on the left side of the window casing.

By a reversal of these movements the screen vframe 15 may be mounted again on the guide Inembers'13; s

It is the intention to have the manufacturers of the window casings furnish said casings tothe builders with the metal guide members 13 mounted thereon to be installed in the building during its construction, and

then when the screens are to be supplied no accurate measurements will be required for the reason that knowing the general width of the window casing screens for substantially that width may be forwarded and quickly installed.

This is of great advantage as screen frames may be made in quantities and supplied of the general width of any size window and installed quickly, thus saving the labor of men going to the, building, taking accurate measurements of the casings, and then constructing the screen frames in accordance with the measurement-of each particular window.

It isbelieved that the operation and many advantages of the invention will be understood without further description.
